11.2 DIRECT AND BENDING STRESSES

Let a rectangular column subjected to a compressive force p acting along the axis of the column (Figure 11.1(a)) be considered. This force will cause a direct stress whose intensity will be distributed uniformly across the cross section of the column. That is

 

 

where p_o = the intensity of direct stress

        A = area of cross section

Let a similar column be subjected to a compressive force P whose line of action is at a distance e from the axis ...
